Abstract

This study sought to determine whether preprocedural lesion morphology differentially affects the outcome of directional coronary atherectomy versus standard balloon angioplasty. Despite previous studies (Canadian Coronary Atherectomy Trial [CCAT]/Coronary Angioplasty Verus Excisional Atherectomy Trial [CAVEAT]), directional coronary atherectomy continues to be recommended on the basis of lesion-specific features, although the validity of this approach has never been proved. A retrospective, subgroup analysis of the CCAT data base (group average +/- SD) was performed. In the long term (6 months), both procedures were equally successful in the proximal left anterior descending coronary artery (directional atherectomy 0.62 +/- 0.70 mm vs. coronary angioplasty 0.70 +/- 0.72 mm, p = NS), with atherectomy tending to perform best in relatively "simple" lesions (American College of Cardiology/American Heart Association [ACC/AHA] type A: atherectomy 0.57 +/- 0.70 mm vs. angioplasty 0.50 +/- 0.77 mm; ACC/AHA type B1: atherectomy 0.65 +/- 0.68 mm vs. angioplasty 0.60 +/- 0.68 mm) and those with moderate dystrophic calcification (atherectomy 0.79 +/- 0.56 mm vs. angioplasty 0.45 +/- 0.73 mm). Although greatest minimal lumen diameter gains...Continue Reading
